Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of using wood for an outdoor building, in which the durability of the wood is improved and the wood is used as a member for building an outdoor building.

[0002]

2. Description of the Related Art Japan is a forest country, and tree planting is carried out all over the country. Therefore, a large amount of thinned wood such as cedar and cypress is generated. Some of the thinning materials generated in large quantities are used as construction members for outdoor structures such as pasture fences, protective fences, signposts, stair steps such as natural sidewalks, earth retaining members, etc. Conventionally, thinned wood cut from mountain forests may be used as a building material as it is, or in order to prevent the occurrence of rot etc. due to penetration of rainwater etc., an alkylammonium compound-based preservative etc. is pressurized in advance. In some cases, it is used after being subjected to preservative treatment such as pouring, applying creosote oil or the like, or being used after painting.

[0003]

However, if thinned wood cut from a mountain forest is used as a construction member as it is, it is advantageous in terms of cost, but is susceptible to decay due to permeation of rainwater and the like. It is difficult to maintain and manage under severe conditions where rainwater and the like are often infiltrated, and in some cases, it is necessary to replace decayed ones.

[0004] On the other hand, when used with preservative treatment,
Although durability is improved, it is disadvantageous in terms of cost and it is very troublesome because it is necessary to bring it to a preservative treatment facility, and many preservatives are harmful and environmentally friendly. I am concerned. In particular, creosote contains a carcinogenic substance, and thus has a problem in disposal treatment. In addition, when used after painting, maintenance is not easy, such as the need to repaint frequently.

Accordingly, the present invention solves the above-mentioned problems and, when using wood as a construction member for an outdoor building, easily and without impairing the environment, preventing the penetration of rainwater and the like, and making the wood durable. It is intended to provide a method of using wood for outdoor construction, which is used by improving wood.

[0006]

In order to achieve the above object, the present invention has the following arrangement. That is, the method of using wood according to the present invention for an outdoor building includes, when using wood as a building member of the outdoor building, attaching a bottomed cylinder to at least one of both end portions of the wood. It is a feature.

According to the present invention, when wood is used as a construction member for an outdoor building, a bottomed cylinder is attached to the end of the wood, and the bottomed cylinder allows penetration of rainwater and the like from the end. Can be prevented, and the durability of wood as a construction member of an outdoor building is improved.

Moreover, even when thinned wood locally cut down is used as a building member for an outdoor building constructed locally, there is no need to transport the thinned wood to a preservative treatment facility, and the bottomed cylinder is not required. By simply sending the body to the site and attaching it to the wood, the durability of the wood can be improved, which is advantageous in terms of cost and ease, and there is no problem of environmental destruction due to the preservative.

In the present invention, when wood is used as a construction member of an outdoor building, when the wood is erected and the lower part is buried in the soil or on a concrete foundation, the top and lower buried parts of the wood are used. If the bottomed cylindrical body is attached to the bottom, it is possible to prevent penetration of rainwater and the like from the top and penetration from the lower buried portion.

When wood is used as a construction member for an outdoor building, when the wood is used horizontally, it is preferable to attach bottomed cylinders to both ends of the horizontally provided wood.

The bottomed cylinder may be formed of a metal such as an iron-based or aluminum alloy, but is preferably formed of a synthetic resin having excellent durability. It is preferable to use a polyolefin-based synthetic resin such as polyethylene or polypropylene, which has little problem of environmental destruction.

[0012] If thinned wood is used, effective use of the thinned wood can be achieved. The thinned wood that has been cut and selected is cut into a predetermined cross-sectional shape, for example, a rod shape such as a round bar or a square bar, a flat plate shape, a hollow shape, etc., so that it can be used as a construction member for an outdoor building. Cut to length.

The outdoor construction according to the present invention is not particularly limited. For example, in a road maintenance project, forest management, road construction, and park maintenance project, the construction of forest retaining roads, legal frameworks, guideposts and fences, etc. Prevention of rock fall fence, waterway and steps, etc., earth retaining and law frames constructed by sabo works, earth retaining constructed by road construction, fences, information boards, signs, car stops, wind-proof snow fences, sand-proof fences and avalanche prevention Fences, such as fences, benches, wooden bricks and five-sided curbs, constructed in the park construction.

Next, an embodiment of the present invention will be specifically described with reference to the drawings. FIG. 1 is a partial cross-sectional front view showing an embodiment of a method of using wood for an outdoor building according to the present invention, and FIG. 2 is another embodiment of a method of using wood for an outdoor building according to the present invention. FIG. 3 is a perspective view showing an embodiment in a case where a method of using wood according to the present invention for an outdoor building is applied to a fence.

First, in FIG. 1, reference numeral 1 denotes a method of collecting thinning materials obtained when a standing tree is cut to an appropriate density in order to grow a vibrant forest, selecting trees, and selecting the selected thinning materials. Wood which has been appropriately processed into a cross-sectional shape, a round bar shape in this embodiment, and cut to a predetermined length. When used as a construction member of an outdoor building, the wood 1 is erected, and the lower part is laid in the soil or concrete. It is used buried in the foundation.

Reference numeral 2 denotes a bottomed tubular body which is mounted on the top 11 and the lower buried portion 12 of the wood 1 to prevent penetration of rainwater or the like from the top 11 and the lower buried portion 12. 21 covering the edge of the wood 1 and a peripheral wall 22 covering the outer periphery of the end of the wood 1
And formed from. The bottomed cylindrical body 2A attached to the top 11 of the wood 1 is short enough to cover the end face and the end edge in order to prevent penetration of rainwater or the like from the top 11.

The bottomed cylindrical body 2 mounted on the lower buried portion 12
B is for preventing penetration of rainwater or the like from the ground or soil, and therefore, when the lower buried portion 12 of the wood 1 is buried,
Is set to have a length protruding to some extent from the ground G so as not to contact the ground G. Also, assuming that rainwater or the like may enter, the drain hole 23 for discharging the infiltrated rainwater is provided at the bottom 21.
May be provided. In this case, since the bottom 21 has a small amount of oxygen, the activity of the decay fungus is slow, and the drain hole 23 has little effect on the wood 1.

The bottomed cylindrical body 2 may be fixed to the wood 1 by a fixture 3 such as a nail or a wood screw, may be adhered with an adhesive or the like, or may be simply fitted.

Next, FIG. 2 shows a case where the wood 1 is used in a horizontal state when the wood 1 is used as a construction member of an outdoor building. In this case, rainwater from the left and right end portions 13 is used. In order to prevent permeation, etc., a short bottomed cylindrical body 2C is attached to the left and right end portions 13.

The wood 1 is made of thinned wood processed into a round bar shape in the same manner as the form shown in FIG.
Is fixed to the wood with a fixture 3 such as a nail or a wood screw.
